We report mutimodal imaging findings of an extraskeletal chondroma of the Hoffa's fat pad. Plain radiographic or CT scan studies demonstrate a large soft tissue mass with calcifications and central ossification, characteristic features of these tumors. Magnetic resonance (MR) imaging shows heterogeneous signal due to polymorphic histopathological appearance. Correlation between MR imaging and p...

In pectus excavatum, a developmental chest-wall deformity that affects approximately one in 400 births, the sternum is depressed inward and the ribs protrude anteriorly. This deformity can compromise pulmonary and/or cardiac function. It can also produce a characteristic radiographic appearance on frontal radiographs, which may be mistaken for right-middle-lobe opacification from pneumonia or a...

Numerous techniques have evolved for acromioclavicular joint fixation over the past decade to help decrease the risk of hardware complications and improve patient satisfaction. One of these techniques involves the TightRope system, which employs two titanium endobuttons to help reduce and secure the coracoclavicular joint. Clinical outcomes have been favorable, as orthopedic surgeons have gaine...

The radiographic appearance of the petrotympanic fissure, through whic h the chorda tympani nerve exits the tympanic cavity, is familiar to radiologists as a normal struc ture, not to be mistaken for a frac ture of the anterior wall of the external auditory canal [1, 2).

A 6-year-old girl visited our department, in the absence of any other systemic abnormalities, on clinical and radiographic evaluation, it was revealed that she had only 6 primary teeth in her mouth. Maxillary and mandibular removable partial dentures were fabricated for prosthodontic rehabilitation. At the 6 months follow-up nutrition of the patient a...

The radiographic appearance of the paranasal sinuses is less accurate in infants and children than in adults, as in infants the cavities are smaller and the margins of the healthy sinuses are often indistinct Moreover, the details of the infantile cranial bones themselves are not sharp owing to the lesser contrast in density between relatively thin bones and soft tissues of the infantile skull ...

The osteoma is a benign osteogenic neoplasm of bone. Peripheral osteoma of the mandible is uncommon. It is often asymptomatic and usually discovered when a patient complains of esthetic problems and presents for treatment. Peripheral osteomas have a characteristic clinical and radiographic appearance, but their pathogenesis is obscure. Described here are two patients with peripheral osteoma of ...

A rare case of talon cusp on geminated permanent central incisor is described. These developmental anomalies cause clinical problems including unsightly dental appearance, occlusal interference, displacement of the affected tooth, attrition, periodontopathy, irritation of the tongue, loss of space and malocclusion. Clinical and radiographic characteristics of these anomalies and modes of treatm...

Introduction: Gastritis cystica profunda (GCP) is a rare tumor which occurs more commonly in patients with prior gastric surgery. The nonspecific symptoms and radiographic appearance of this tumor mimic that of other hyperproliferative conditions making diagnosis difficult without definitive surgical resection. This report provides a comprehensive review of GCP and all GCP cases reported to dat...
